我知道,无论Watchers与Observers就将计算在东西$scope在AngularJS变化.但无法理解两者之间究竟有什么区别.

我最初的理解是Observers为角度表达式计算,这是HTML一侧的条件,Watchers执行$scope.$watch()函数时执行.我在想什么？

我有一个auto-carousel指令迭代链接元素的子元素.

然而,子节点尚未加载到DOM中,因为它们ng-if的表达式尚未被解析.

如何确保父指令知道它的DOM树有变化？

        <ul class="unstyled" auto-carousel>
          <li class="slide" ng-if="name">{{name}}</li>
          ...
          <li class="slide" ng-if="email">{{email}}</li>
        </ul>

我可以使用,$timeout但感觉不可靠.我也可以使用ng-show而不是ng-if但不回答问题,而不是我需要的问题.

我使用这个程序github.com/vasyabigi/angular-slick.它不适用于动态数据.它只适用于静态数据.在动态数据中,它显示水平放置的垂直图像,没有Carouseling.请帮助我.这是我的精力充沛
